Except as otherwise provided in this rule, evidence of the following is
not, in any civil or criminal proceeding, admissible for or against the
defendant who made the plea or was a participant in the plea discussions:

(1) A plea of guilty which was later withdrawn;

(2) A plea of no contest;

(3) Any statement made in the course of any proceedings under
Article 58 of Chapter 15A of the General Statutes or comparable procedure in
district court, or proceedings under Rule 11 of the Federal Rules of Criminal
Procedure or comparable procedure in another state, regarding a plea of guilty
which was later withdrawn or a plea of no contest;

(4) Any statement made in the course of plea discussions with
an attorney for the prosecuting authority which do not result in a plea of
guilty or which result in a plea of guilty later withdrawn.

However, such a statement is admissible in any proceeding wherein
another statement made in the course of the same plea or plea discussions has
been introduced and the statement ought in fairness be considered
contemporaneously with it. (1983, c. 701, s. 1.)
